Download or read book Population Limitation in Birds written by Ian Newton and published by Academic Press. This book was released on 1998-04-08 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book meets the demand for a comprehensive introduction to understanding the processes of population limitation. Recognized world-wide as a respected biologist and communicator, Dr. Ian Newton has now written a clear and detailed treatise on local scale population limiting factors in birds. It is based almost entirely on results from field studies, though it is set in a contemporary theoretical framework. The 16 chapters fall under three major section headings: Behavior and Density Regulation; Natural Limiting Factors; and Human Impacts. Population Limitation in Birds serves as a needed resource expanding on Dr. David Lacks research in this area of ornithology in the 1950s. It includes numerous line diagrams and beautiful illustrations by acclaimed wildlife artist Keith Brockie. Provides a sorely needed introduction to a long-established core subject in ornithology Focuses on local scale factors Written by a well-known biologist and effective communicator Includes numerous line diagrams and beautiful illustrations by acclaimed wildlife artist Keith Brockie
Download or read book Handbook of Natural Pesticides Methods written by N. Bhushan Mandava and published by CRC Press. This book was released on 2018-04-19 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook series includes several naturally occurring chemicals that exhibit biological activity. These chemicals are derived from plants, insects, and several microorganisms. Volume I of this series is covers the theory and practice of the strategies for pest control and methods for detection.Moreover, it presents extensive tables that provide the information you need to select the most appropriate bioassay for a particular plant growth regulator or hormone. In addition to the chapters on bioassays, Volume I provides a solid introduction to the theory and practice of natural pesticide use, including in-depth discussions of integrated management systems for weed and pest control, the state-of-the-art use of computers in pest management, and allelochemicals as natural protection. Guidelines on toxicological testing and EPA regulation of natural pesticides are also detailed.

Download or read book Pest Control Cultural And Environmental Aspects written by David Pimentel and published by CRC Press. This book was released on 2019-07-15 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of pest control research, of increasing importance in a world short of food, has been plagued for many years by a variety of problems, among them (1) the instability (including pesticide resistance) of many control techniques, (2) the continuing need for improved pest management methods to increase world food supplies, and (3) the environmental and social hazards of currently used pesticides. What historical or other factors affect the ability of science to generate useful new technologies to alleviate these three major problems? Are there barriers to cooperation among the different pest control specialists? This book attempts to answer these questions, examining past events and projecting likely impacts on contemporary pest management systems. The authors--sociologists, economists, lawyers, ecologists, political scientists, and pest control scientists--examine the social, economic, political, and ethical factors that are important in shaping pest management systems, as well as developmental patterns that show the importance of these factors in shaping today's systems.
